The vatu was introduced in 1981, one year after independence, to replace the New Hebrides franc at par. The vatu was issued as a single unit with no subdivision, with the 1 vatu coin being the smallest denomination issued, in a similar vein to the Japanese yen and the Tajikistani ruble.

The ISO 4217 currency code for the Vanuatu vatu is VUV. Its nationally recognized symbol Vt is the most often used in written format. The vatu's introduction also saw the end of the official circulation of the Australian dollar in Vanuatu.

Vanuatu's first post colonial coin was a 50 vatu coin introduced in 1981 and commemorated independence. It was struck in cupro-nickel like previous issues and was released into circulation, though originally its release was targeted more towards collectors. Shortly thereafter, in 1983, 1, 2, 5, vatu coins were released in aluminum bronze and 10, 20, and 50-vatu coins were introduced in cupro-nickel, replacing the coinage of the New Hebrides Franc as the new circulation currency. This also replaced the Australian currency that was circulating in the British controlled islands. All Vanuatu coins depict the Vanuatu coat of arms, consisting of a native warrior in front of a whorled pig's tusk, a traditional item of value. The reverses depict other traditional items of value.

Due to Vanuatu's French colonial history, the current vatu coins have the same size and coloration of the coins of New Hebrides which are based in part on French units, particularly the 1, 2, and 5 vatu in their similarity in size and composition to the 5, 10, and 20 centimes of the old French Franc. The 10, 20, and 50 vatu bear some similarities to Australian coins but are actually slightly larger with closer approximate size to coins of similar valuation to those in New Caledonia, and French Polynesia. In 1988, a nickel-brass 100 vatu coin was introduced, this coin replaced the 100 vatu note. The coin is of the same size and general thickness of the British 1 pound coin.

In 2011 the Reserve Bank of Vanuatu ceased to issue 1 and 2 vatu coins, which had become infrequently used due to inflation.[2] Prices in Vanuatu stores are now rounded to the nearest 5 vatu.

On 22 March 1982, notes were introduced by the Central bank of Vanuatu in denominations of 100, 500, and 1,000 vatu.[4] These officially replaced franc notes of the former New Hebrides. In 1988 the 100 vatu note was withdrawn from circulation and replaced by a 100 vatu coin. In 1989, 5,000 vatu notes were introduced.

In 1993, after a financial restructure, the Reserve Bank of Vanuatu took over paper money issuance and introduced newly designed notes for 500 and 1000 vatu. 200-vatu notes were first introduced in 1995 to cut down on the amount of 100 vatu coins received in change and the need to meet demand by producing more. In 2011, new 5,000 vatu notes were also issued in polymer.[5] Polymer 10,000 notes were issued as a commemorative issue on 28 July 2010. As of 2013 they are no longer in circulation.[1]On 9 June 2014, the Reserve Bank of Vanuatu introduced a new series of notes printed on polymer, among the new series of notes is a new denomination of 2,000 vatu, in addition to regular 10,000 vatu notes.[6]

Local residents sometimes refer to a notional dollar, equal to 100 vatu, without specifying which country's currency they have in mind. This stems from the period 1966–1973, when the New Hebrides franc was pegged to the Australian dollar at a rate of 100 francs = 1 dollar. Although no relationship currently exists, it simplifies thinking in the larger numbers which a low-value unit causes. For example, the Government's budget of 6,000,000,000VT is in fact only about US$50,000,000.

In some Vanuatu languages, in which counting in large numbers is cumbersome and not well known, 10 vatu is colloquially referred to as "one shilling", and 200 vatu is referred to as "one pound". For example, in Apma language, "50 vatu" would be selen kalim "five shillings".[7] This roughly reflects the historical exchange rate of the vatu against the pound, although since 2008 the number of vatu to the pound has been significantly lower than this.

Many communities in Vanuatu continue to conduct ceremonial business such as the paying of fines and bride-prices using traditional items of value, such as pigs, curved boars' tusks and long dyed mats. Vatu is sometimes used as a substitute for traditional valuables in such ceremonies, although the National Council of Chiefs discourages this.

The Tangbunia indigenous bank, based on Pentecost Island in Vanuatu, offers accounts and transfers denominated in livatu, a unit of currency equivalent to the value of a fully curved boar's tusk.
